微量灌洗法是检测支气管肺泡灌洗(BAL)回收液中上皮衬液(ELF)量的新技术。研究旨在①建立周围气道灌洗的新方法,并与常规的 BAL 法进行比较;②对计算 ELF 总蛋白浓度的可重复性予以评价;③探讨常规 BAL 直接用尿素稀释法回收 ELF 量是否估计过高。方法与结果①为探讨充满远端肺段所需的灌洗液量、灌洗时间及回收方法,而对10例正常死者进行肺右中叶和舌段灌洗.全部肺均用18ml,但20个亚段中18个只用15ml 即可充满,注入时间少于20s.回
The micro-irrigation method is a new technique to detect the amount of epithelial lining fluid (ELF) in bronchoalveolar lavage fluid (BAL) recovery fluid. The aim of the study was to establish a new method of peripheral airway lavage and to compare with the conventional BAL method, to evaluate the repeatability of calculating the total protein concentration of ELF, to investigate whether the amount of ELF recovered by conventional BAL directly by urea dilution Estimated too high. Methods and Results ① In order to investigate the amount of lavage fluid, lavage time and recovery method required for the distal segment of the lung, the right middle lobe and tongue segment of 10 normal subjects were lavaged, A sub-paragraph of 18 only 15ml can be filled, injection time less than 20s
